I love this one:
"Between persons of equal income there is no social distinction except the distinction of merit. Money is nothing: character, conduct, and capacity are everything. Instead of all the workers being levelled down to low wage standards and all the rich levelled up to fashionable income standards, everybody under a system of equal incomes would find her and his own natural level. There would be great people and ordinary people and little people, but the great would always be those who had done great things, and never the idiots whose mothers had spoiled them and whose fathers had left them a hundred thousand a year; and the little would be persons of small minds and mean characters, and not poor persons who had never had a chance. That is why idiots are always in favor of inequality of income (their only chance of eminence), and the really great in favor of equality."
(George Bernard Shaw, "The Intelligent Woman's Guide to Socialism", cited by Howard Zinn in "Passionate Declarations", chapter "Economic justice: the American class system")
